Tabular linked states

[ryanomite]

Describe the feature

I have dozens of automations that set the state of one entity based on a change of the state of another entity (for example, door open → light on). Instead of manually creating automations for each of these "linked states", I'd love to create/maintain these in single, tabular format. Architecturally, these would still be implemented using automations, but that would be abstracted out with a dedicated UI interface (e.g., Settings → Automations & Scenes → State Linkages). In addition, many of these automations exist as "complementary" pairs (i.e. one to turn on the light when the door opens, one to turn if off when the door closes), so it'd be nine for this feature to support complementary actions when binary states are involved.

I understand that this could probably be abstracted out a little with blueprints, but I still feel that the maintenance overhead is just too high for something that's an extremely common use case.

Use cases

Door open → Light switch on (and complementary action of Door close → Light off)
Home occupied (binary sensor) → Scene on
Motion detected → siren on

Current workarounds

Multiple repetitive automations that I must manually create and maintain.

Anything else?

FWIW, I'm happy to develop this... just wanted to "test the waters" in case this already been suggested or ruled out.
